Since it explored Pluto in 2015, the New Horizons spacecraft has been zooming toward NASA's most distant target yet. Join the mission team as the probe attempts to fly by Ultima Thule, an object 4 billion miles from Earth.
Astrophysicists show how black holes might hold answers to how the universe evolved, leading to life on Earth and, ultimately, the human race.
Could scientists recreate Hollywood's Jurassic Park using 100-million-year-old dinosaur DNA? Director Steven Spielberg, author Michael Crichton, actor Jeff Goldblum, and a host of scientific experts answer this compelling question in the award-winning Nova documentary, The Real Jurassic Park. Behind-the-scenes clips, interviews, and demonstrations with leading paleontologists investigate the viability of reviving the extinct species. All phases of logistics are addressed, including extracting prehistoric insect DNA, creating embryos for placement in host eggs, and more. The scientific analysis of the process leads to the examination of the ethics of recreating a vanished life form.
Considered the finest example of Byzantine architecture in the world, Hagia Sophia was constructed on a scale unprecedented in human history. Built in the amazingly short time of five years, it bears witness to an amazing scientific knowledge and a rich cultural heritage from the past.
At the dawn of the Christian era, Petra, capital of the rich kingdom of the Nabataeans, bordering the deserts of Arabia, Syria and the Negev, was absorbed by the Roman Empire and, after being sacked by the Bedouins, disappeared from the memory of mankind; but its secrets are gradually being revealed thanks to an enormous excavation work.
Three million years ago, camels roamed through Greenland’s endless forests and our ancestors lived in the trees. It all came to an end with the Ice Ages. What died and what survived, as natural selection shaped the evolutionary tree during this epochal shift from hot to cold? Until now, scientists have known less about the natural world before the Ice Age than they did about the age of dinosaurs, which ended 64 million years ago. A new discovery is set to reveal this lost world, species by species. Led by Danish gene-hunter Eske Willerslev, a team of scientists for the first time in history is sequencing DNA from before the Ice Age. The picture that emerges is of a hot planet, when forests blanketed the Arctic and carbon levels matched those in our atmosphere today. Is this a portrait of our own climate future?
Earth teems with a staggering variety of animals, including 9,000 kinds of birds, 28,000 types of fish, and more than 350,000 species of beetles. What explains this explosion of living creatures—1.4 million different species discovered so far, with perhaps another 50 million to go? The source of life's endless forms was a profound mystery until Charles Darwin brought forth his revolutionary idea of natural selection. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? To what degree do different animals rely on the same genetic toolkit? And how did we evolve?
Predictions underlie nearly every aspect of our lives, from sports, politics, and medical decisions to the morning commute. With the explosion of digital technology, the internet, and 'big data,' the science of forecasting is flourishing. But why do some predictions succeed spectacularly while others fail abysmally? And how can we find meaningful patterns amidst chaos and uncertainty? From the glitz of casinos and TV game shows to the life-and-death stakes of storm forecasts and the flaws of opinion polls that can swing an election, 'Prediction by the Numbers' explores stories of statistics in action. Yet advances in machine learning and big data models that increasingly rule our lives are also posing big, disturbing questions. How much should we trust predictions made by algorithms when we don't understand how they arrive at them? And how far ahead can we really forecast?
In 1889, Gustave Eiffel decides to attempt the impossible for the Universal Exhibition in Paris: to build the tallest tower in the world. Before this project, this pioneer and visionary had created more than 300 metal structures around the world.
David Attenborough brings to life, in unprecedented detail, the last days of the dinosaurs. Palaeontologist Robert DePalma has made an incredible discovery in a prehistoric graveyard: fossilised creatures, astonishingly well preserved, that could help change our understanding of the last days of the dinosaurs. Evidence from his site records the day when an asteroid bigger than Mount Everest devastated our planet and caused the extinction of the dinosaurs. Based on brand new evidence, witness the catastrophic events of that day play out minute by minute.
A post-modern theater adaptation of a classic Greek tragedy takes place in a central theater of Athens. Like every night, the audience take their seats and the play begins. Suddenly, the lights on stage go out. A group of young people, dressed in black and carrying guns, come up on stage. They apologize for the interruption and invite people from the audience to participate on stage. The play resumes with a main difference; life imitates art and not the opposite.
The collaboration between architects, scientists, archaeologists and engineers in their efforts to restore Notre Dame.
Leonardo da Vinci was a Renaissance genius. Not only did he paint masterpieces of art, but he was an obsessive scientist and inventor, dreaming up complex machines centuries ahead of his time, including parachutes, armored tanks, hang gliders and robots. On the 500th anniversary of Leonardo’s death, with the help of biographer Walter Isaacson, NOVA investigates the secrets of Leonardo’s success. How did his scientific curiosity, from dissections of cadavers to studies of optics, shape his genius and help him create perhaps the most famous painting of all time, the "Mona Lisa"?
Archaeologists believe that a massive grave in a vicarage garden in Derbyshire may be the last resting place of a vast army of thousands of warriors that invaded Britain in the ninth century.
Twenty-three bizarre looking vehicles line up at the starting gate of the DARPA Grand Challenge with one thing in common: there's nobody behind the wheel. Sponsored by the Pentagon's research agency, this race for robotic, driverless vehicles has a $2 million prize. Its ultimate goal is to gather new ideas for the future of unmanned warfare.
Determined to understand the repeating patterns he was finding in nature, French mathematician Benoit Mandelbrot used an early form of computer imagery to produce his own versions, coining the recurring shapes fractals. This installment of the PBS series "Nova" examines the rules of these self-similar patterns and explores the ways these fascinating geometric configurations can be applied in the fields of science, medicine and the arts.
Murdered more than 5,000 years ago, Otzi the Iceman is the oldest human mummy on Earth. Now, newly discovered evidence sheds light not only on this mysterious ancient man, but on the dawn of civilization in Europe.
The Vikings were the most ferocious warriors of the Middle Ages. Especially fearsome were the select few who wielded a formidable weapon: a light, razor sharp, virtually indestructible sword with its maker's name, Ulfberht, inlaid along the blade.
The events and coincidences that led to rapid advances in human intelligence 50,000 years ago.
